Constraint Validation: Native Client Side Validation for Web Forms Introduction Validating forms has notoriously been a painful development experience. Implementing client side validation in a user friendly, developer friendly, and accessible way is hard. Before HTML5 there was no means of implementing validation natively; therefore, developers have resorted to a variety of JavaScript based solutions. To help ease the burden on developers, HTML5 introduced a concept known as constraint validation - a native means of implementing client side validation on web forms. Yet, despite being available in the latest version of all major browsers, constraint validation is a topic largely relegated to presentations and demos. In this tutorial I will: Present a comprehensive overview of what constraint validation is. What is Constraint Validation? The core of constraint validation is an algorithm browsers run when a form is submitted to determine its validity. As an example take this form with an empty required text input: Try It willValidate validity validationMessage

La gestion des événements en JavaScript Cet article est une introduction aux notions nécessaires pour bien comprendre et utiliser les événements en JavaScript. JavaScript est un langage événementiel : le développeur a un contrôle limité sur le flux d'exécution du code, qui est déterminé principalement par les interactions avec l'environnement (activation d'un lien, mouvement de la souris, chargement du contenu du document, …). La gestion des événements est un sujet essentiel dans le cadre de ce langage. Le DOM niveau 0, standard de facto hérité de Netscape ; il s'agit de l'interface la plus largement supportée mais aussi la moins puissante. Les concepts présentés dans la suite de l'article sont communs à ces trois familles, sauf indication contraire. L'objet Event Un événement est un changement d'état de l'environnement qui peut être intercepté par le code JavaScript. Ce changement d'état peut être provoqué par l'utilisateur (pression d'une touche, ...), par le document (chargement d'une image, ...), ou même par le développeur.
Automatic Image Montage with jQuery Arranging images in a montage like fashion can be a challenging task when considering certain constraints, like the window size when using fullscreen, the right image number to fill all the available space or also the size of the images in use. With the following script you can automatically create a montage, either for a liquid container or a fixed size container (including fullscreen), with the option to fill all the gaps. View demo Download source Having a white space in the end of the container can, as well, be avoided optionally. Another option that can be useful in some cases is the possibility to only allow that the height of all images will be the height of the smallest image, avoiding that any picture gets pixelated/enlarged. The images used in the demos are by Andrey Yakovlev & Lili Aleeva. The HTML structure Simply put the images that you want to use in the montage into a container with the following class (the ID is used to call the plugin then): Options

Hoverizr – An in depth view of the jQuery plugin As a web designer, from time to time, you may need to make a grayscale image fade into color on mouse over. So the typical solution would be to have each image desaturated to achieve the grayscale effect in Photoshop. Then, you would have to add a few extra divs and image tags to the markup an then add some jQuery magic to fade the images in and out. Or, you could have merged two images into one larger image with double the height and play around with background positioning in the CSS and Javascript files. Lets have a look at the pros and cons of each of those two solutions: Pros: • If you use an image sprite (both images in one file) then you have one less HTTP request for each image. Cons: • You have to manipulate each image separately, which means that the client might not be able to update images with that effect dynamically and it is a time consuming proccess.• If you use two images then you will have many HTTP requests. Enter the canvas element. Now let’s dive in. Hoverizr Part 1.
